1. Process Brief

Lime slurry reacts with chlorine to generate calcium hypochlorite and calcium chloride. Calcium chloride has high solubility. Generally, it is completely dissolved in water, while calcium hypochlorite is only partially dissolved, and most of it is precipitated in the form of crystallization. This crystallization is filtered and separated, and dried to make bleaching powder. The effective chlorine recovered from the mother liquor can be sold as disinfection or bleaching solution, or calcium chloride dehydrate can be crystallized by evaporation after treatment.
